AMERICAN A CORPORA- PAT ENT OFF ROLLING-MILL GUIDE.

Application filed June 6, 1927. Serial "No, 196,752.

This invention relates to improvements in guides for use on the delivery side of sheet and plate mills and more particularly for use on the delivery or catchers side of sheet and plate roughing mills,' and has for its object the provision of a novel form of guide and guide support whe'reby theguide will be supported entirely on the support and "free of the rolls.

.In the draWingS- Figure l is a sectional elevation through a stand of rolls havingithis invention applied thereto.

Figure 2 is a top plan of the gu1de-rest-bar and guides removed from the mill.

Figure 3 is an enlarged sectional elevation through the guide rest-bar and guide.

Referring more particularly to'the drawings, the numeral 2 designates the rolling mill housings which are, of the4two high type and have rolls 3 journaled therein in the usual manner.

A guide plate 4.--is mounted on the roller s or feed-in side of the mill over which the roller slides the sheets or plates when teeding them into the bite of the rolls 3.

On thedelivery or catchers side of the mill I have provided an angle shaped guide rest-bar 5 which extends horizontally between and is secured to the housings 2. The bar 5 is arran ed with one flange 6 extending horizontal y and with its other flange 7 extending vertically upwardly neat to the rolls 3.

The bottom or horizontal flange 6 .is provided with a pair of longitudinally extending slots 8 which are enlarged at their inner ends at 9 and are undercut along their longitudinal edges as at 10 for a purpose to be described. 7

. A pair of sheet receiving guides A. and B are mounted on the rest-bar 5 and each comprises a substantially wedge shaped hody portion 12 having a transverse groove 13 therein, adapted to fit loosely over the flange 7 of the bar 5 so as to provide for a limited rocking movement or" the guides relative to the. bar 5. The body portions 12 are provided with a rearwardly projecting 14, adapted when the guides positioned on the her 5,1to overlie the bottom flange 6 oi the bar 5. The flanges 14+. of the are apertured at 15 to receiveholts 16 which holts are mounted in the slots E5 in the bottom flange 6 of the bar 5.

flange "he understood that I guides and said bolts are then moved along the slots 8 so that their heads will be engaged in the undercut portions 10 of the slots 8'.

Thebolts 16 extend upwardly through the slots 8 and through the apertures 15 in the flanges 1d of the guides A and B and have Ia'djusting nuts 17 and .18 threaded thereon to lock the guides in position.

Coiled springs 19 are mounted around each of the bolts 16' between the flange 6 of the guide bar5 and the flanges 14 of the guides and serve to form a resilientand yieldable support forthe rear ends of the guides A and B.

The forward ends of the guides A and B are adapted to terminate just short of the surface of the lower mill roll 3 at a point slightly below its top surface so as to receive the sheets fed between the rolls and yet clear the rolls and thus prevent wearing of the guides and rolls.

hen the rolls 3 are re-surfaced or new rolls are substituted having a diflerent diameter than the rolls for which the guides A and B have been set the guides may be readily reset or adjusted by simply unscrewing the nuts 17 and 18 which will permit the a springlQ to expand and rock the guides A. and B about the flange 7 of the guide restbar 5, thereby tilting theguides toward and closer to the rolls 3.

Ti new rolls of a larger diameter than those originally in the housing are substituted for the worn rolls, it will be necessary to reverse the operation of the nuts 17 and 18, that is', screw down the nuts in order to compress the spring 19 and rock the guides 'A and B about the flange 7 of the guide restbar 5, thereby tilting thegu-ides upwardly and away from the rolls 3.

In order to adjust the guides transversely for difierent sizes of sheets it is only necessary to loosen the, nuts 17 and'18 and slidethe guides'A and B transversely along the rest-bar. r

While I have shown and described one specific embodiment of my invention it will do not wish to be limitcd thereto since various modifications may made without departing from the scope nv invention as defined in the appended July 3, 192a. 1,675,821
